Fig. 3 is the arrangement schematic diagram of guidance set in the embodiment of the present invention, in conjunction in Fig. 3 embodiment of the present invention, each cunning
A guidance set 7 can be set between dynamic yoke 3 and spud leg 1, so that sliding yoke 3 can only be moved along the length direction of spud leg 1
It is dynamic.
Each guidance set 7 of the embodiment of the present invention may each comprise a protrusion and a guide pad 703.
Fig. 4 is the scheme of installation of the guide plate of guidance set in the embodiment of the present invention, and in conjunction with Fig. 3 and Fig. 4, the present invention is real
The protrusion applied in example includes two carrying gussets 701 and a connecting rib 702, and two carrying gussets 701 are along 1 length of spud leg
Direction is oppositely arranged, and one end of two carrying gussets 702 is fixed on the outer wall of spud leg 1, the other end of two carrying gussets 701
It is connected by connecting rib 702, the two sides of connecting rib 702 protrude from carrying gusset 701, and such protrusion is formed one
A π type structure.
Fig. 3 and Fig. 4 is recombined, the guide pad 703 of the embodiment of the present invention is mounted on sliding yoke 3 towards the side of spud leg 1
On, there are two guide grooves 704 for the setting of guide pad 703, and the two sides of connecting rib 702 are slided be plugged in guide pad 703 respectively
In guide groove 704.
The effect of the guidance set 7 of the embodiment of the present invention is: when wedge bracket 2 is moved along 1 length direction of spud leg, connection
The two sides of gusset 702 are moved in the guide groove 704 of guide pad 703, and sliding yoke 3 can be constrained on spud leg 1, make to slide
Yoke 3 only can cannot be controlled or be moved forward and backward with oscilaltion campaign.
The guidance set 7 of the embodiment of the present invention is avoided due to being arranged between sliding yoke 3 and spud leg 1 to sliding
The guiding mechanism of yoke 3 is arranged in inside wedge bracket 2, has reasonably saved the space inside wedge bracket 2.
Since connecting rib 702 protrudes the outer surface of spud leg 1, each column pin hole 6 can be made to be arranged in each connection
The distance between yoke 3 and 1 ontology of spud leg are slided to expand in the middle part of gusset 702, generate when avoiding sliding yoke 3 mobile with spud leg 1
Interference.
In the case where ensuring a=0, the distance c on surface of the adjustable carrying gusset 701 to spud leg 1, as long as guaranteeing to mention
The distance between the surface of oil-lifting jar 4 and spud leg 1 b is not less than 100mm.
Fig. 5 is the arrangement schematic diagram of pin hole in the embodiment of the present invention, in conjunction with Fig. 5, due to the lifting under the arrangement form
The plugging pin oil cylinder 5 for being device can be bigger, and therefore, the pitch-row d of each column pin hole need to be not less than 2000mm.
The carrying gusset 701 of the embodiment of the present invention can be mounted on by welding on the outer surface of spud leg 1, and be connected
Connecing gusset 702 can be fixedly connected with two carrying gussets 701 by welding.
In addition, after due to being inserted at the pin hole 6 at the middle part of connecting rib 702 by plugging pin oil cylinder, connecting rib 702, two
The outer surface of a carrying gusset 701 and spud leg 1 can form an enclosure space, avoid the appearance of carrying gusset 701 and spud leg 1
The attachment weld in face is by seawater corrosion.
The sliding yoke 3 of the embodiment of the present invention can be equipped with a side plate 304 towards the side of spud leg, and guide pad 703 is logical
Screw 305 is crossed to be detachably arranged on the side plate 304.
Guide pad 703 in the embodiment of the present invention can be made of two mounting blocks, and two mounting blocks are separately mounted to insert
The two sides of oil cylinder 5 are sold, guide groove 704 is arranged in mounting hole towards on the side of plugging pin oil cylinder 5, to avoid mounting blocks and promotes oil
Cylinder 4 interferes.
In addition, the surface hardness of the guide pad 703 of guidance set need to be less than connecting rib 702 in the embodiment of the present invention
Surface hardness, when the end of connecting rib 702 is moved in the guide groove 704 of guide pad 703, the two can rub, due to
The surface hardness of guide pad 703 need to be less than the surface hardness of connecting rib 702, and therefore, meeting preferential wear surface hardness is lower
Guide pad 703, since guide pad 703 can be with dismounting and change, it is thus possible to increase the service life of device.
Further, the wedge bracket 2 of the embodiment of the present invention includes top plate 201, coaming plate 202 and bottom plate 203,201 He of top plate
Bottom plate 203 is connected by coaming plate 202, and top plate 201 and bottom plate 203 are passed through by spud leg activity, and such wedge bracket can form one
A only vertically communicated hemi-closure space, can prevent the internal component of outer bound pair wedge bracket 2 from corroding to a certain extent, increase
The service life of feeder apparatus.
The section of the spud leg 1 of the embodiment of the present invention can be circle, or other shapes such as rectangular, regular polygon
Shape.
The working principle of the hydraulic bolt lifting device of the embodiment of the present invention are as follows:
Spud leg 1 is fixed, and the plugging pin oil cylinder on each sliding yoke is inserted into corresponding pin hole, realizes sliding yoke and spud leg
Locking, the telescopic end elongation of lift cylinder, makes wedge bracket that ocean platform be driven to rise along spud leg；
Wedge bracket drive ocean platform along spud leg rise to subscribe stroke after, fix ocean platform, on each sliding yoke
Plugging pin oil cylinder extracted from corresponding pin hole, realize the separation of sliding yoke and spud leg, the telescopic end of lift cylinder retracts, makes
Each sliding yoke rises along spud leg；
Each sliding yoke repeats aforesaid operations, completes the rising of ocean platform after spud leg rising in place；
The decline of ocean platform and the rising principle of ocean platform are similar, and the embodiment of the present invention does not repeat them here this.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
